Product Description
Perform liquid-liquid extractions on milligram-scale samples without losing product to oversized glassware. These small Squibb-type funnels fit 14/20 jointed setups, so they can drain straight into a flask or double as addition funnels for microscale reactions in teaching and research labs.
